How reliable are the Tasmota'ed Sonoffs in the long run? (Share your experience and/or configuration please)

Now I understand what you mean. All my Sonoff devices show frequently disconnects :frowning: and some disconnects are quite long:

I found this link: GitHub - arendst/Tasmota: Alternative firmware for ESP8266 and ESP32 based devices with easy configuration using webUI, OTA updates, automation using timers or rules, expandability and entirely local control over MQTT, HTTP, Serial or KNX. Full documentation at

If I understand it well there are wifi disconnect issues with all 6.4.x based on the 2.4.x core. It is recommended to try with Core 2.3.0 or dev build with beta core 2.5.0

The sonoff-tasmota firmware based on based on the 2.5.0-beta2 core is released here: http://thehackbox.org/tasmota/020500/

If I understand it well, this should be done using the serial connection. Or can I update using an over the air update as well?

Did anyone try this?
